Description
Technical field
The utility model relates to a kind of motor driving type electronic lock, is specifically related to a kind of motor driving type electronic lock core.
Background technology
It is strong that electronic lock has level security, authorizes modifiable advantage.Electronic lock is common in hotel and the industrial occasions such as house unit entrance and electrical equipment cabinet uses; There is the trial of to be expanded by electronic lock in family expenses in recent years, but because of many reasons, fail penetration and promotion.Trace it to its cause, except the factor of marketing aspect, motor driving type electronic lock core internal construction is complicated, and poor reliability is also one of principal element.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, the motor driving type electronic lock core of good reliability.
The utility model discloses a kind of motor driving type electronic lock core, exterior ring cap is had outside lock core, this lock core comprises plug body and is built in propulsive mechanism wherein, plug body offers T-shaped hole, the radial hole the inner in T-shaped hole is cecum, the built-up member of pushing ram and spring are built-in with in radial hole, the built-up member of hollow-cup motor and flat wheel are built-in with in axial hole, spring is placed on the inner of pushing ram, its one end is fixed in the cecum plug body of radial hole, the other end is fixed on pushing ram, pushing ram there is C type groove, flat wheel is connected on the output shaft of hollow-cup motor, its outer end is arranged in C type groove, the other end of hollow-cup motor has key insertion hole, during hollow-cup motor no power, pushing ram stretches into exterior ring cap, lock cuts out, powered to hollow-cup motor by key, the flat wheel that rotarily drives of hollow-cup motor output shaft rotates, and flat wheel drives pushing ram Compress Spring, realizes unlocking action.
Described pushing ram is the cylindrical rod that successively decreases successively of three sections of diameters from outside to inside, and maximum diameter cylindrical section length is the longest; The internal diameter of described spring is less than the diameter of maximum diameter cylindrical section, is greater than the diameter of interlude cylinder, and the natural length of spring is not less than length and the pushing ram effective travel sum of pushing ram beyond maximum diameter cylindrical section.
Described C type slot is in the maximum diameter cylindrical section of described pushing ram, and the groove width of C type groove is greater than the radius of described flat wheel.
The effective travel of described spring is greater than pushing ram when lock cuts out and stretches into the length of exterior ring cap part.
When key does not insert, hollow-cup motor does not work, and spring is in micro-compressive state, and pushing ram stretches in the hole of exterior ring cap, and plug body cannot be rotated relative to exterior ring cap, and lock is in closed condition; After hollow-cup motor starts, hollow-cup motor drives flat wheel to turn clockwise, and flat wheel stirs pushing ram Compress Spring, and in pushing ram retraction plug body, now plug body can be rotated relative to exterior ring cap, and lock is unlocked.
The utility model is simple and reliable for structure, be easy to processing, and replaceable all kinds of mechanical lock core, is beneficial to the popularization of electronic lock.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
Fig. 2 be in Fig. 1 A to enlarged drawing.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model discloses a kind of motor driving type electronic lock core, it comprises plug body 1 and propulsive mechanism 2; Plug body 1 is for offering the cylinder in T-shaped hole in middle part; Propulsive mechanism 2 comprises spring 21, pushing ram 22, flat wheel 23 and hollow-cup motor 24, and propulsive mechanism 2 is installed in the T-shaped hole of plug body 1.
Pushing ram 22 is three sections of diameters cylinder single piece of successively decreasing successively from outside to inside, wherein maximum diameter cylindrical section length is the longest, the external diameter of spring 21 is less than the diameter of maximum diameter cylindrical section, the natural length of spring 21 is not less than length and the pushing ram effective travel sum of pushing ram 22 beyond maximum diameter cylindrical section, the end face of the maximum diameter cylindrical section of pushing ram 22 is fixed in spring 21 one end, the other end is fixed in plug body 1 that T-shaped aperture is to cecum, and the effective travel of spring 21 is greater than pushing ram 22 when lock cuts out and stretches into the length of exterior ring cap 3 part.The maximum diameter cylindrical section of pushing ram 22 has groove width be greater than C type groove that flat takes turns 23 radiuses, flat wheel 23 is connected on the output shaft of hollow-cup motor 24, its outer end is arranged in C type groove, the other end of hollow-cup motor 24 has key insertion hole, powered to hollow-cup motor 24 by key, the flat wheel 23 that rotarily drives of hollow-cup motor 24 output shaft rotates, and flat wheel 23 drives pushing ram 22 Compress Spring 21, realizes unlocking action.
When key does not insert, hollow-cup motor does not work, and spring is in micro-compressive state, and pushing ram stretches in the hole of exterior ring cap, and plug body cannot be rotated relative to exterior ring cap, and lock is in closed condition; After hollow-cup motor starts, hollow-cup motor drives flat wheel to turn clockwise, and flat wheel stirs pushing ram Compress Spring, and in pushing ram retraction plug body, now plug body can be rotated relative to exterior ring cap, and lock is unlocked.
The utility model is simple and reliable for structure, be easy to processing, and replaceable all kinds of mechanical lock core, is beneficial to the popularization of electronic lock.
